To all whom t may concern:

Be it known that I, LEROY S.`Lnw1s,'a citizen ot the United States, residing at Springeld, 1n the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Apparatus for Automatically Supplying Lamps and other Burners with Oil, of which the following is a specitication. h

This invention relates to improvements in apparatus for burning hydrocarbon, the same being designed for utilization for both illu minating and heating purposes.

The invention particularly relates to improvements in a regulator for automatically deliverlng the oil for consumption, the same having adequate capabilities for the positive and sensitive governing action, for the absolute shut ott and avoidance of leakage when the-burner or burners are not lighted; for adjustment whereby the height of oil Vmay be as deslred in the service or regulator tank fount or founts; and, moreover, the apparatus 1s designed with especial reference to the greatest simplicity and cheapness of production, consistent with efticiency.

In the accompanying drawings,in Sheet 1 the apparatus is shown as embodied in an oil burning chandelierlight for ahouse, while 1n Sheet 2 the new regulating apparatus is shown as applied to both an oil stove, and a street light; and in said drawings, Figure l is a vertical sectional view of the chandelier burner with a pendent telescoping support and the novel devices of this Vinvention applied thereto. Fig. 2 is a plan view of the regulator drum and regulator levers, as seen below the plane indicated by the line 2 2, F 1g. l. Fig. 3 is an enlarged vertical sect1ona1 view of the packing for the joint between the sections of the telescoping pendant. Flg. 4 is a sectional view through the valveseat which is provided adjacent the regulator, the valve also being shown therein. Fig. la 1s a sectional View of a modification of the valve seat. Fig. 5 represents the strainer device.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the supply tank which may be at any suitablyv elevated place, and which may supply oneor several lamps, chandeliers, or burners.

B indicates the chandelier, the pendent support for which consists of the upper vertical stationary section, a, and the lower vertically sliding section, b, which telescopes the section, a, and extends below the lower end thereof. The -supply pipe, c, leads from the supply tank, A, to a suitable connection with the upper end of the depending section, a, while within and below the said\ section, a, is the vertical tube, d, which, at its lower end, is connected to move as one with the surrounding telescoping section, b, and the chandelier or burner devices carried thereby. The said tube extends upwardly within the section, a, to a point higher than that to which the upper end of the outer telescoping section, b, is projected. The valve devices, operated by the regulator float, are arranged within the suitably formed lower end of the tube section as will be hereinafter described; and the said tube, d, is extended through the packing at the lower end of tube section, a, for a close sliding tit, but one which, never-v theless, is oil tight and which is constituted substantially as follows, reference being had to Figs. 1 and 3:-A short distance above the lower end of the tube section, a, is firmly brazed, or otherwise secured, the collar, d2, with the flaring opening in the lower part into which the fibrous packing, d3, is placed to surround the pipe, d. Awasher', d4, is provided next below the packing, d3, closely titting the interiorof pipe, a. The annular plug nut, 017, screws into the lower screw-tapped end of the pipe section, a, loosely through which an intermediate part of the tube, el, passes; the upper part of the plug nut, C17, is upwardly flaring receiving therein also a fibrous packing, d3, overlaid by the washer d6; these parts are so arranged that there is a considerable space between theV two washers within which I place, before assemblage of all the parts, a heavy, pasty substance which I compound as follows:one part mutton suet, four parts glycerine, two parts plumbago, one part parafline, and one part beeswax, which majT be united by heating and stirring IOO together. Through the so formed packing there can be no oozing or leakage of the petroleum, or other form of the hydrocarbon employed, down between the vertical tube, d, and the tube, a.

I do not desire to confine myself to the exact combination or proportion of the ingredients above set foi'th, but these have been found by me to be very effective and advantageous.

The tube, d, below the last described joint is of increased diameter for the accommodation of the valve devices, andthe tube section, b, is also correspondingly enlarged. The enlargement of the tube, b, has at its lower end the collar, f, with the radially extended arms', f2,

which constitute the support for the regulator tank, g, the cap, g2, thereof being removable. The regulator tank has, at its bottom, the depression, g, for the connection of the chandelier arms or branches which extend to and support and feed the lamps, m. 7i represents the float or drinn within the regulator tank. ft' represents the valve controlled thereby and j represents the valveseat. The valve-seat is separately formed within the lower end of the vertical tube, d, by a sleeve section, 3'2, having the inwardly extended annular ribs, ja, with the circular Haring open ings within them, and with the annular spaces between them. This valve seat is non-metallic and is composed of a hard, impervious, non corrosive, and slightly elastic substance, as is also the valve., Such a substance may be produced by digesting wood or other fiber for the production of a pulp, mixing with such pulpa small quantity of shellac, and then bringing the whole into a solid,dry and hard condition. The valve-seat may be integrally formed of the aforesaid material, as represented in Fig. 4,01*, as represented in Fig. ft, it may be composed of several ofthe hardened ber rings which areheld separated by the in termediate spacing sleeve sections, j, which are externally screw-threaded and screw into the pipe section in which the valve-seat is comprised. As the conical valve (the seat bearing portion of which I also preferably form by said hardened fibrous material) moves axially to its seat the annular lips or ribs may yield or be dedected slightly permitting the valve and seat to more closely conform the one to the other.

The spaces intermediate between the annular valve-seatlips, j, constitute annular traps or cushions of accumulated air which, furthermore, reduce the liability of the leak age of oil at the valve while closed. The valve il, has the stem 7c, upwardly and downwardly projected therefrom. The upwardly projected part of the valve -stem has the weight 7a2, while the lower part of the stem has the disk m, with the doubled beveled or V-edge. Surrounding the lower portion of the tube, d, within which is said valve-seat, is a sleeve, u, which is vertically adjustable by sliding, being held in place by the setscrew which passes through the aforesaid collar f. This sleeve has the depending arms n2, ou the lower ends of which the levers, o, 7o

0, o, of the regulator are toward their inner ends, pivotally connected. The inner arms ,of the levers are bifurcated, or specifically, l have Vrecesses within their ends which eugage the doubly beveled edge of' the Valvestem-disk, m. The outer extremities of the said levers, o, enter the apertured lugs, p,

y which project above the top of the regulator drum.

`angles to the direction of swing of said levers, having spring capabilities, which conduce to a better operation of the regulator dc- `f vices, overcoming any inequalities in the rising and falling mcveinents'of the regulator l drum, and obviatng any tendency to abrupt 1 or violent closure of the valve to the seat.

It is desired to havey the governing devices adjustable so as to be set for the height of oil z at any level within the regulator tank. The fulcruni supports for the regulator levers are, L therefore, vertically adjustable about and relative to the valve-seat, by the means def scribed as consisting in the collar, n, and the set screw, n2, therefor, so that by either raising or lowering such fulcrum support the nor- 1 mal level of the oil in the tank will be higher or lower, as consequent upon the correspondingly higher or lower position of the tioat at the time the valve is closed upon its seat.

The valve-seat with the tube, d, is also vertically adjustable relative to the tank and section, giving larger scope to the adaptability for varying the normal oil level iu the regulator tank, and this is insured by forming the collar, u, slotted as seen at n3, so that the set screw, b3, may be passed through the collar, f, (which surrounds the lower end of telescop ing tube section, 1),) and, without interference with the collar, u, carrying the levers to a detachable connection with the valve -seat tube, (Z.

For practicability of construction and asi semblagc, the tube, d, is formed in sections,

screw united substantially as shown in Fig. l, or as the convenience of the constructor may demand or indicate as advantageous.

In the drawings here given, the upper section of the tube, d, has at its lower end the inverted cup-like enlargement, da, externally screw-threaded, while the upper end of the enlarged lower tube section is internally IOO res

be manifest that in the raising or lowering ot the chandelier, or the maintenance thereof stationary, there can be no leakage of oil upwardly between the tube sections, a, b, to the upper end of the latter.

One or more straining devices are provided 1n the oil conduits of the apparatus which are composed as follows: Sheets of line wire gauze are tightly rolled to form a plug, t, of cylindrical form, and driven into the pipes suitably near the coupling thereof. Thus is formed a very efcient strainer for the oil. k

In practice I prefer to have one edge of the sheet of the gauze, from which the rolled up plug is formed, angular to its opposite edge, whereby a depression,t2, is formed in the end of the strainer plug, which relative to the oil flow, is rearward.
